E4OD 2-3 shift issues
I have a 96 F250 460 4x4 with an E4OD. Tranny was rebuilt about 10k miles ago. I'm having issues with the 2-3 shift. Everything was working great parked it to go into the store and came out and had no 2-3 shift. I can make it shift manually but not in Drive. I have checked the harness and it looks good. Also did a continuity check and it was good from the trans connection to the pcm. I checked the valve body and the 2-3 spring was sticking out. At that point I found a rebuilt valve body and stuck it in. Took it for a test drive and the same issue. Pulled the valve body back out and everything looked good and moved freely. Looking for any ideas. Thanks for the help.

Check for codes and check your transmission fluid level.
Who rebuilt the transmission? Did you call them?
Does 4x4 work and does the dash light for 4x4 work? If you truck thinks it is in 4x4 low it won't shift right.

There are no codes and the fluid level is in the middle of the hash marks.
I rebuilt the tranny.
I will check the 4wd. It worked the last I used it but I don't recall if the lights came on or not.

It's really cool that you rebuilt your own E4OD.
Is the 2-3 shift problem new or has it done it since the rebuild or even before the rebuild?
Do you have the ATSG or Ford manuals?
My 1991 will flash the OD light to indicate problems. Does the 1996 have the equivalent?
Did you drive it in 4Low and does the same problem persist in 4Low?

It was a fun project.
The problem is new. It literally happened after I shut it down. Everything was working great after the rebuild.
Yes, the 96 flashes the of light when there's an issue. I was thinking it was some sort of electrical issue but the harness checks out good. I'm leaning towards an issue with the solenoid. I used a rebuilt one instead of new.

All my diagnostic information is older, for my truck and I don't have access most of it anyway.
The solenoid or the valve, it could be either. Or something else.
I tried to get some more knowledgeable transmission guys involved.

I have found that it will shift into third when the rpms are around 3500 with the od light off. But if I turn the of light on it won't shift to third at any rpm.
Not sure if this is a solenoid or pcm issue. Any ideas?

Finally had time to work on the tranny. I pulled the vb and inspected for broken springs and sticking valves and all looked good. Then pulled the accumulator and did the same. All was good. Replaced both gaskets and filled it with fluid. And sure enough the problem is still there.

Thanks Sandymane. I will take a look at the PCM when this weekend. I have check codes and there were none. I have checked the wiring from the PCM to the solenoid and all is good. Thanks for the help.

If it goes into 3rd sometimes, by manipulating the O/D cancel button, it's probably not a valvebody issue.
There are three sensors primarily used for shifting: TPS, VSS and MLPS. If any one of those are erratic or intermittent, you will have shifting problems. Does your speedometer bounce around, or is it smooth?

The speedo is smooth. The last time I checked the tps it was within the ranges. I will check the tps this weekend. Thanks for the tips.
The only way to get it to upshift to 3rd is to move the shifter from M2 to D. It shifts the same if the od light is on or off. It down shifts into all gears just fine.
